Figure 3. Physical properties of NP-laden GelMA hydrogels and in vitro release profile of NP/miRNA from hydrogels.

Figure 3.

(A) Swelling ratio, and (B) degradation rate of GelMA hydrogels loaded with varying concentrations of NPs in GelMA polymer in DPBS buffer (pH 7.4). (C) In vitro release profile of miRNA released from GelMA/NP/miRNA hydrogels in DPBS, and (D) enzyme induced release of miRNA from GelMA/NP/miRNA in the presence of 100 μg/ml collagenase type II in DPBS, 48 h post-incubation.
